Q:
# the radius of a spherical beach ball is 24 cm.If another spherical beach ball has a raduis 3cm longer, about how much greater is its surface area to the nearest square centimeter ?

Accepted Solution

A:

Answer:1923 cm²Step-by-step explanation:The surface area of a sphere is A = 4πr².The first spherical beach ball has a radius of 24 cm:A = 4π (24)²A ≈ 7238 cm²The second spherical beach ball has a radius 3 cm greater, or 27 cm:A = 4π (27)²A ≈ 9161 cm²So the difference in area is:9161 - 72381923 cm²
